Well, I got the M551 Sheridan replacing the M41 as Light Tank, and airborne.
M551 replaced this M114 as far as recon role, but that's a complicated lineage.
I think M551 is better suitable as a modern day ancestor to WW2 light tanks.
M114 was also used to complement the bigger M113, AFAIK.
The idea of yours with armored cars coming in to this M114 (and airborne, and equal perhaps the British Fv101 Scorpion) finally making any of the modern unit-made arm cars. That's a good idea.
The Bradley is kept as IFV-Mech Infantry lineage from the M113.
The Stryker should also find a role in this upgrading way, somehow
Problem today is that so many great units are being made and it's hell (pleasant one) to fit them into the game.
Needs some thinking on this
but a drop.flc with the M114 will help along to be sure.
Whatever Great Thanks for these very nice units mate
